Python wrapper for the Zeo++ library. Based on the latest released version 0.3.

We provide pre-built wheels for most platforms (including Apple Silicon). So in most cases you will want to install the package with pip:

pip install pyzeo

If you wish to install the package directly from the source code, you can do so with:

git clone https://github.com/nomad-coe/pyzeo
cd pyzeo
pip install .

Note that this type of installation will require a separate, platfrom-dependent compilation step. These are some common problems you may encounter in the compilation step:

• fatal error: Python.h: No such file or directory: The package depends on C/C++ extensions that are compiled during the setup. For the compilation to work you will need to install the pythonX.X-dev-package, where X.X is the python version you use. E.g. for python 3.9 on Ubuntu this package could be installed with:

  .. code-block:: sh

   sudo apt install python3.9-dev
  

• Installation errors on MacOS: The package depends on C++ extensions that are compiled during the setup. If experiencing problems with setup on MacOS, you may need to install the Xcode Command Line tools package. This can be done with:

  .. code-block:: sh

  xcode-select --install
  

By default the package comes with pre-built Cython binding code. The cython wrapper definitions live inside src/pyzeo. These bindings can be recreated by first setting USE_CYTHON=True in setup.py, and then recreating the bindings with:

python setup.py build_ext --inplace --force

Remember to disable cython afterwards by setting USE_CYTHON=False in setup.py.
